|Professional audio production, editing, and mixing techniques - Dowse, Justin Michael|
The purpose of this thesis is to demonstrate professional and efficient music production and music mixing techniques. This is not meant to be a definitive answer to the endless approaches that can be used in music production and mixing. Instead, it is intended to aid learning in a profession where there are no black and white answers since choices in music production and mixing are highly dependent upon the engineer's preferences...

|Lost in translation: the queens of Beowulf - Horton-Depass, Laura Ann|
The poem Beowulf has been translated hundreds of times, in part or in whole. In past decades translators such as Howell Chickering and E. Talbot Donaldson firmly adhered to formal equivalency, following the original text line-by-line if not word-by-word. Such translations are useful for Anglo-Saxon students but cannot reach a larger audience because they are unwieldy and often incomprehensible. In the past fifty years, though, a group of translators with different philosophies has taken up the t...

|Preparing teachers to work with english learners: exploring the potential for transformative learning in an online enlgish as a second language for educators course - Dewing, Stephanie E.|
The number of English language learners (ELLs) in the United States school system is growing rapidly. Much of the responsibility for teaching ELLs lies with regular classroom teachers. However, little training is being provided to help them. From a sociocultural perspective and drawing on constructive-developmental theories of adult learning and development, this study explores the potential for transformative learning in a one semester online English as a Second Language for Educators course...

|Heidegger's discourse on Heraclitus's Concepts of Logos and Aletheia - Rainer, Kristopher Stephen|
his paper maintains that the work of Heidegger on Heraclitus' fragments 50 on logos and 16 on aletheia, represent a viable alternative to the "Metaphysics" of Occident Thinking in the early 20th century, which has culminated in the mindset of the our technological age. It further explores an alternative aspiration for language and methodology that is able to serve as a viable alternative for the exploration of Heraclitus' texts, given their fragmentary format and obscure nature...

|ENERGY HARVESTING FROM MICROBIAL FUEL CELL USING SELF-SYNCHRONOUS FLYBACK CONVERTER - Alaraj, Muhannad|
Microbial Fuel Cells (MFCs) use biodegradable matter, such as wastewater and animal droppings to generate electrical energy. To harvest the energy from MFC, power electronic converters have recently been used because of their advantages, such as the ability to store the harvested energy and the ability to control MFC voltage. Although power electronic converters have advantages to be used to harvest the energy, the diode based energy harvesters suffer from the low efficiency because of the diode...

|PRACTICAL METHODS FOR CRITICAL LOAD DETERMINATION AND STABILITY EVALUATION OF STEEL STRUCTURES - Fernandez-Mora, Pedro|
The critical load of a column, compression member or structure, calculated from a linear elastic analysis of an idealized perfect structure, does not necessary correspond with the load at which instability of a real structure occurs. This calculated critical load does not provide sufficient information to determine when failure, due to instability of the structure as a whole, will occur. To obtain this information it is necessary to consider the initial geometrical imperfections, eccentricities ...

This research project studies a selection of Paraguayan short stories by Josefina Pla (Fuerteventura 1903 -Asuncion 1999). Through the exploration of certain motifs she associated to Paraguayan history; her characterization of female protagonists; and the insertion of animate and inanimate objects she uses to mask a denunciation of social, cultural, ethical, and gender issues of the Paraguayan microcosm, this thesis seeks to contribute a fresh critical perspective to the limited body of academic...

|The spatial pattern of economic rents and urban land value model around an airport area: the case study of suvarnabhumi international airport, thailand - Bejrananda, Chakarin|
With the rise of the importance of air transportation in the 21st centuries, the role of economics in airport planning and decision-making has become more important to the urban structure and land value around it. The relationship between the airport and land value in urban areas has attracted more attention from academic researchers. However, there has been little research on the factors that affect the prices of land relatively to the airport location.Using New Bangkok International Airport (S...

|LUMPEN ABUSE AND METHADONE MAINTENANCE: THE IMPACTS OF HIDDEN VIOLENCE ON RETENTION, SATISFACTION AND ABSTINENCE - Ziegler, James|
Philippe Bourgois and Jeff Schonberg pioneered the theory of lumpen abuse, expanding on and integrating Marx's concept of the lumpen proletariat, Bourdieu's symbolic violence and Foucault's biopower and Levi's politics of the gray zone. Lumpen abuse as a theoretical lens can reveal a wealth of insight studying marginalized populations. This study looks at the impacts of lumpen abuse and symbolic vulnerability among Denver MMT clients and discusses the hidden forms of everyday violence that impac...

|The dialectical environment of the mind: a philosophical foundation for biomimicry in the theories of G.W.F. Hegel and Jean Piaget - Windle, Robert Richard, III|
Biomimicry is a technological approach to engaging with the natural world which looks to nature as an intellectual source to solve human problems. The current problems of environmental degradation and the challenges of long-term sustainable production have given rise to the practice of biomimicry. This new form of technologically engaging with the world is reflective of a certain relationship between self and object...

|English language literacy for the native speaker - Blake, Christine Ellen|
The desire to learn a new skill or polish an old one for better employment prospects inspires many adults to enroll in community colleges. However, being away from school for a long time or having struggled in K-12 schooling, can make that transition back to the classroom difficult for adult students. As part of enrollment, they take an entrance exam, and if they do not perform well one the English Reading and Writing portions, they may be identified as "illiterate" in Academic English, and are ...

|Fault detection and isolation in low-voltage dc-bus microgrid systems - Candelaria, Jared M.|
Unlike traditional AC distribution systems, protection has been challenging for DC systems. Multi-terminal DC power systems do not have the years of practical experience and standards that AC power systems have. Also, the cur- rent power electronic devices can not survive or sustain high magnitude faults. Conveters will shut down to protect themselves under faulted conditions. This makes locating faults in DC system difficult, and causes the DC bus to de- energize...

Violence against Mexican women is not a new subject. Disappearances and murdered women in the border town of Cd. Juarez and throughout the country are reported in the news headlines every day. Between 1999 and 2005 more than 6,000 women and girls were murdered, an average of 1,000 murdered women every year. The majority of the deaths result from violence within their household (Mexico, 2009). The rate of violence is not isolated to border towns...

|Examining the differential effects of natural and synthetic aromas of lavender and peppermint on cognition, mood, and subjective workload - Cavanaugh, Jamie Lynn|
There is reliable, empirical evidence that various inhaled aromas can significantly affect mood, cognition, physiology and behavior (Herz, 2009). However, the literature often does not document whether natural or synthetic fragrances were used when evaluating these factors. Also, no studies to date have compared natural and synthetic versions of the same odors. The current study attempted to determine whether the natural aromas of lavender and peppermint were superior to their synthetic counterp...

There is a growing body of evidence suggesting there are modifiable vascular and metabolic risk factors for Alzheimer's disease (AD). Despite many plausible mechanisms by which obesity could contribute, its etiological contributions remains unclear. We therefore investigated 1) the evidence linking obesity to cognitive health, 2) whether obesity in early or mid-life is associated with cognitive change and the possible factors involved, and 3) whether dietary interventions that reduce weight impr...
